my 1985 190e 2.3 failed California smog. The readings that failed were HC - 203 at 15 mph and 223 at 25 mph vs 135 and 110 max. the CO measurements were 2.17 at 15 mph and 2.05 at 25 mph vs max of .83 and .63. I think it could be just fuel injection adjustments (running too rich). Please provide some insite if you would. Thanks.
